The topic of internet trolls has been frequently in the headlines in recent weeks following a number of high-profile incidents.

Olympic Bronze Medal winner Tom Daley was targeted on social networking site Twitter in the first week of the Games, and was reportedly told that he had 'let down' his father in the diving competition.

British swimmer Rebecca Adlington, who also made a podium finish at London 2012, has also been the target of abuse on Twitter.

And even politicians are not immune to being abused online.

Louise Mensch, who announced that she was stepping down as an MP this week in order to spend more time with her family, was the subject of hurtful remarks and threats over the internet.

In her victim impact statement read to the court after the case went to trial, Mrs Mensch revealed the fear that the email had caused her.

Louise Mensch, who resigned as an MP this week, is one of a number of high-profile figures to have been targeted online

'I
was terrified on behalf of my children. I was in New York with my
husband recovering from an operation and my children were with their
father and to receive a threat like this made me very upset,' she said.

'I
was 3,000 miles away from my children and I was worried for their
safety and the safety of my ex-husband. I felt powerless to do
anything.'

And given the apparently growing number of stories relating to online trolls, Lady Gaga is bound to find an eager listener in the Prime Minister on the subject.
